RESILKE'NT TIRE FR VEHICLES.

and are adapted to prevent lateral movement of the bridge ring; the rimand the elly of the wheel with relation to one another.

F is a tirerpreferably formed of a continnous coil of wire, itsperiphery F', being substantially semi-circular in Acrossesection whilecertain portions of the coils F2 cent to the rim are given a V-shapedformation spanning the. bridge ring l); these in turn alternate withportions bent outwardly forming relatively small loops f whichcollectively serve as a bead `Fpengaged by the flanges C and the bridgering D. G denotes cross plates respectively lodged in the 4slots d ofthe bridge rin ;-the `ends g of the cross plates j of the tire F, toprevent the of the tire on the rim.

H is a right and left threaded bolt respecltively engaging the opposing"ends of the bridge ring,'j-the bolt is provided with a central head Hintegral therewith, having recessesvh to receive a pin or other suitabletool by which it may be actuated.

I is a bridge plate set in the recesses formed in thetop of the bridgering to close the space between the opposing sections.

J is a tread or shoe inclosing the tire F land which may be formed ofleather or other suitable material, to which is secured I a lining J offelt.

K indicate hooks or other suitable securing devices engaging the wirerings L placed on each side of the tire,-the ends of the rings L beingin turn joined together by the loops L or other means for securing thesame. v

The tread or -shoe J may be studded with `rivets jby which the cover andits lining are secured together,-the projecting ends creeping tireagainst skiddingn Having indicatedthe several lparts by referenceletters, it will be seen that the petire will aii'ord great resiliencywhile its secures the tirefrom being torn oif through any great lateralstrain due to the vehicle turning suddenly while traveling at a highrate of speed. The arms of the V-shaped portion bearing against thewalls of the bridge ring offer great resistanceV to the wrenchingtendency occasioned through operating under these conditions.

culiar shape given to the coil forming the' extending aterally from lthe Wall of the bridge ring between the loopsof the rivets providingmeans to secure the V-shaped portion spanning the bridge ring Byalternating the- V-shaped portion of the coil spanning the bridge ringwith loops bent to form collectively a'bead lodged between the ring andthe flanges of the rim, means are provided to securely lock the tire tothe rim while tlie cross plates Gr, carried by the bridge ring, serve tosecure the tire against creeping on the rim, as will be readilyunderstood.

It will be seen that an excessive load er when traveling over stones ordeep ruts, the tendency to break is relieved by the V-shaped portionbearing upon the bridge ring which action resultsl in relieving thebending strain of the coil, par,- ticularly of that portion adjacent tothe rims, the result being a gradual flattening of the tire whichafterward springs back to its original form.

Having thus described I claim is l. In a resilient tire for vehicles, acoil of wire having an annularform to encircle the rim of a wheel,certain of the coils being looped outwardly adjacent to the rim of thewheel to`collectively form securing edges on opposite sides of the tire,a bridge ring secured to the lrim of the wheel and adapted to coperatewith said Coil of wire to prevent lateral deflection of the coil ofwire, said ring having a plurality of slots in its inner surface, andplates secured in said slots of the ring and adapted to project betweenthe outwardly looped edges of said certain coils to prevent creeping ofthe coil of wire.

2. In a resilient tire for vehicles, a coil of wire formed annularly toencircle the rim of a wheel, certain of the coils being bent inwardly toform an internal annular depres- 40,sion, said'bent coils alternatingwith a plu rality of others looped at the side of the tire thereof tocollectively form securing edges onV opposite sides of the tire wherebythe tire may be secured to the wheel, and an annular bridge ring securedto the rim of the wheel and adapted to project into said depressionformed in the tire and normally iout of contact with said depression,the sides of said depression beingl adapted tocontact with said bridgering on lateral strain placed on 'the tire whereby the tire is securedagainst latertl dislodgment or strain. 3. 1 In a resilient tire forvehicles, a coil of wire formed annularly to encircle the rim of awheel, certain of the coils being bent inwardly to form a substantiallyternal annular depression, said bent my invention, what oils alternatingwith a plurality of others looped outwardlyv at the `side of the tire tocollec`- tively form securing edges on opposite sides of the tirewhereby the tire may be secured tothe wheel, and an annular bridge ringsecured to the rim of the wheel and adapted to p project into said Vshaped depression 5 formed in the tire and normally out of conwhenoperating under' tact withr said depression, the sides of said lateraldepression being adapted to contact witlrsaid ring on lateral strainplaced on the tire whereby the tire is secured against lateraldislodgment or strain, a cover tread embracing the outer surface of thelire, and means to secure the cover to t'fe tireg.

4f. In a resilient tire for vehiclefdiieels, a coil of wire formedannularly to encircle the rim of the wheel, the ends of the wire andcertain of the coils being looped outwardly to form securing edges onopposite sides o the tire, other coils being defieciedlinwardly toprovide an annular substantially V-shaped depression, and an annularbridge ring secured to the rim of the wheel and adapted t project intothe V-shaped depression and being normally spaced from the depression,the V- shaped depression of the tire being adapted to contact with saidbridge ring to prevent lateral strain on the tire.

5. In a resilient tire for vehicles,'a coil of wire having an annularform to encircle the rim of a wheel, certain of the coils being bentinwardly in substantially a V-shaped form, said coils ,s lternating withothers looped outwardly acent to the rim of the wheel to collectivelyform beads on each side of the tire, a bridge ring adapted to be securedto the rim of the wheel and to project int-o the V-shaped depressionformed in the tire, said'bridge ring slotted to receive a plurality oflaterally projecting plates, and the plates adapted to project betweenthe looped portions of the coils whereby the tirev 10o is secured fromcreeping.

6. A resilient tire for vehicle wheels, coinprising a coil of wireformedannularly with certain of the coils directed inwardly to form asubstantially V-shaped depression, 105 the other coils being loopedoutwardly to form securing edges on the opposite sides of the wheel, theloops of the looped coils being arranged at the side of the tireopposite the 'tread surface thereof with the depression be- 110 tweenthe tread surface and said looped coils.

7. In a resilient tire for vehicle wheels, the combination with a wheelprovided with a rimiand having spaced clencher rings, an annular bridgering secured to the rim between said clencher' rings,

a coil of wire formed annularly to encircle the rim of the wheel,certain of the coils being bent inwardly to form an annular depressionto rcceive said bridge ring, the latter being normally spaced from thcdepression. said inwardly directed coils alternating with a plurality ofother coils looped outwardly to form annular spring securing edges onopposite sides of t-he tire adapted to fit between the sides of saidbridge ring and tls, inner faces of the corresponding clencher ringswhereby the coil of wire is secured to the rim, said bridge ring beingadapi'cdito bc 130 :connected to 'the bridge ring and coperati coil vofwire formed annular-1y to encircle the rim of the Wheel, certain of thecoils being` ,strain on the tire to the rim,

engaged by saidA depression upon lateral prevent dislodgment of the tireincident to lateral strain, and means lng with the coils which are' looed out@ wardly to prevent lcreeping of the tlre.

8; In a resilient tire for vehicle Wheels, ,the combination with a Wheel4provided with a rim and clencher rings on opposite sides of of anannular bridge ring secured to the rirn between the clencher rings, anda bent to collectivelyl provide securing edges rlngs whereby the tire issecured to the rirr against displacement, and plates secured to theinner surface of the annular ring and projecting between those coilsaforesaid to prevent creeping of the tire on the rim.
